One of the biggest difference is something that happened very recently. Google is much faster at updating then the alternatives for some reason.
I suspect it is about event driven versus polling. That Google is given update when things happen from trusted news sites instead of having to poll or crawl for new things. Would not be surprised Google just has a lot more of these connections than MS has.
But I am probably unusual in that I now just try to keep all my data at Google instead of it being spread around.
A big one is my ISP is allowed to sell my data without even me knowing. So I use Google DNS instead of my ISP and also use YouTube TV. All to try to keep my data away from my ISP.
My biggest issue is companies being hacked and people getting my data like what happened to Yahoo. I just trust Google better able to protect.
